A systematic review comparing low carbohydrate and isoenergetic balanced diets for reducing weight and cardiovascular risk has been published recently. The review evaluated all relevant clinical trials comparing low carbohydrate and balanced diets. The findings show that over 2 years, in overweight and obese people with and without diabetes, the two diets had similar effects on weight, and similar effects on risk factors for heart disease and markers of diabetes. A document summarising the key findings of the review is available for download at this link:
